Uploading to cloud

Help,help..I know that there is a facility in Creative Cloud or Lightroom whereby you can upload images to the cloud and then give someone a link to access these images. I have seen it done at sometime in the past but simpy cannot re-call the way it was done. Can anyone out there point me towards a tutorial of some kind showing this procedure, I have searched but with no luck..Thanking anyone and everyone in anticipation.
